BELECTRIC’s new 3.0 MegaWattBlock is claimed to set new standards in solar power production. The power plant unit is designed to create electricity at the lowest possible levelized costs of electricity (LCOE). On a par with the functionality of large conventional power plants, the grid-stabilizing plant technology is designed to intelligently integrate renewable energy sources in existing power grids.

First Solar has launched a new evolution of its Series 3 CdTe thin-film PV module platform. The ‘Series 3 Black’ is said to incorporate First Solar’s latest advances in conversion efficiency as well as additional features to enhance its performance in utility-scale power plants.

DuPont Microcircuit Materials (MCM) has introduced ‘DuPont Solamet PV416’ photovoltaic metallization paste used to raise the efficiency of thin film photovoltaic cells. The front-side silver paste material has the capability to be processed at temperatures below 140°C, and is designed to provide improved contact resistance, conductivity, adhesion and fine line resolution when printed on Transparent Conductive Oxides (TCOs). The new paste has been claimed to have boosted CIGS thin-film manufacturer, Midsummer AB’s cell efficiencies by as much as 0.5%.

Dr Schenk has developed a high-speed, non-destructive measurement of I-V curves of thin-film modules prior to the lamination step. The SolarMeasure I-V Curve Tracer evaluates the characteristics of every individual cell on the complete thin-film panel and detects local variations. These measurements can be taken in-line and the results serve as a GO/NO-GO test of whether a panel should be processed further.

The photovoltaic-TPA (Thermo Plastic Applicator) from Bystronic glass group is a machine designed for the encapsulation and sealing of thin-film photovoltaic modules. The machine is claimed to be the first machine of this type that is capable of working in 24-hour operation without any interruption.

The NSG Group is a leader in TCO (transparent conductive oxide) coated glass for thin-film photovoltaic applications. Its ‘TEC’ product range is a group of products, including a comprehensive range of TCO coated glass, optimized to suit a variety of thin-film photovoltaic technologies.

Manz AG has launched an XRF-inline quality system (IQ-XRF) as an extension of its Manz IQ Series. The fully automated x-ray fluorescence system has been designed to qualify various deposition process steps in photovoltaic production lines. Two of these XRF-systems were recently integrated into a photovoltaic line and show their ability to perform in 24/7 operations.

With the FPI solar series, dr. schwab IT has developed metrology systems covering all aspects of the production process for thin-film panel manufacturing. The new system meets volume production speed requirements with full surface measurement for quality assurance as well as continuous monitoring of all process parameters helping to increase productivity and yield of production lines.

Now that the PV industry has unquestionably entered a new growth phase, all eyes are on which technologies will win through into the mainstream of PV manufacturing. PERC, n-type, p-type bifacial, heterojunction – all have become familiar terms in the ever-growing constellation of solar cell technologies. The question is which will offer manufacturers what they are looking for in improving efficiencies and cutting costs.

Although the past few years have proved extremely testing for PV equipment manufacturers, falling module prices have driven solar end-market demand to previously unseen levels. That demand is now starting to be felt by manufacturers, to the extent that leading companies are starting to talk about serious capacity expansions later this year and into 2015. This means that the next 12 months will be a critical period if companies throughout the supply chain are to take full advantage of the PV industry’s next growth phase.
